im using matlab 7.4.0 (im not sure which version was it but i think its pretty old) with quartus ii 7.2sp3 and dsp builder ii 7.2 sp3. when install the dsp builder i have the following message appeared on the matlab command window: To get started, type one of these: helpwin, helpdesk, or demo. For product information, visit www.mathworks.com (http://www.mathworks.com). Install type is install Adding path : c:\altera\72sp3\quartus\dsp_builder\bin\matlab Adding path : c:\altera\72sp3\quartus\dsp_builder\bin Adding path : c:\altera\72sp3\quartus\dsp_builder\bin\mdllibrary DSP Builder path saved.

i installed matlab7.4(matlab2007a)and quartus ii 7.2 sp3 and dspbuilder 7.2sp3, both in windows xp and windows vista,everything is ok,and it is only the right version i have installed which did not have errors,also, the quartus 8.0 and matlab2008a also have some problems, You'd better install matlab7.4 first,then quartus 7.2 ,then 7.2sp, then dsp 7.2,dsp7.2sp3,modelsim.Then if you also have some problems, it must be some problems with your windows system.

First of all can you confirm what QUARTUS_ROOTDIR points to? Just type getenv('QUARTUS_ROOTDIR') at the MATLAB command prompt. Next up can you type "sGeneric" at the MATLAB command prompt. You should get an error (even if it's fine - since you didn't give any parameters). Please paste the error text here. And finally can you list the contents of the directory c:\altera\72sp3\quartus\dsp_builder\bin ?

hi.i think you're right,but the compatibilitites of altera'software is not so good,also.the dspbuilder works well depends on not only itself,but also matlab,maybe ug_dspbuilder.pdf which you can download from altera.com is your good teacher,after the installation of matlab and quartus,when you install ipcore and dsp,their directory you'd better select with default.

So was the 7.4.0 you said at the start of this thread a typo? I guess that would explain it.

Did the installer actually recognise your old installation or did you have to manually type in the MATLAB path to make it find it?

Anyway it's good news that you've solved your problem!

I have got Microsoft Vista Sp1 SO

I had installed and running fine DSP Builder 7 with Quartus 7.2 and Matlab R2007b.

Last week I tried to upgrade to the Quartus 8 and I had problems with license.

Then I decided desinstalling all programs and return to the Altera suite 7.2.

Now Quartus and NIOS EDS are running fine, but after installing DSP Builder over Matlab this message of error appears,

did it work well when you initially installed the quartus 7.2 Lite?

bertronicom,

It sounds like you don't have the class path set up properly. At the MATLAB prompt, type:

type classpath.txt

At the bottom, there should be a section like:

# DSPBuilder START
....
# DSPBuilder END

Does it exist and does it point to a file in your current DSP Builder installation?

Hi cLare, dsp builder worked well with quartus 7.2.

dabuk, typing : "type classpath.txt"

there isn't any reference to DSP builder.

With no reference to DSP Builder on the classpath, it's not surprising the installer failed. Could you try reinstalling DSP Builder and see if it changes the classpath.txt file? On my installation this is found at:

C:\Program Files\MATLAB\R2007b\toolbox\local\classpath.txt

Is this file read only for instance? You could for instance add the following to it:

# DSPBuilder START
c:\altera\72\quartus\dsp_builder\bin\dspb_sblocks.jar
# DSPBuilder END

(Obviously make sure the path above matches where you installed Quartus).

I've removed remaining files from uninstallation and installing again Matlab r2007b and DSP builder 7.2 sp3. Then the installation was error free.

classpath have the settings you specified

Now, when matlab is started this error appears and dspbuilder blocks weren't loaded

Sounds pretty bad. Looks like you matlab pathdef.m is corrupt.

I would follow the advice in the error message and try:

restoredefaultpath;matlabrc

That should repair the MATLAB path at least.
